Figure =1 illustrates my. invention as applie'dto a' 'steamrlocomotive' in'which a jpipe line 5 is, tapped into the boiler water -supply,

V v V a 1 It is one-of the objects ofrthis invention to-providera :coupling'that isacapable of. varied uses where it is desired to provide a 'breakable connectionbetween two mem- One of the uses ofm'y invention is in coning the decks. This hose taps into the water supply for the boiler and oftentimes the valve" therein does not properly seat, permitting the same to leak, and 'as'the water isat a hot temperature, numerous serious. accidents result therefrom. My invention is designed to eliminate this danger by providing a fem-ale couplin member adapted to receive the nozzle on t etend of the hosewhen the same is not in use, theireceiving member and nozzle having a water-tight connection and said receiving memberbeing connected with a source of water supply so'thatthe leakage will not be wasted.

A further object ofthis invention is to provide a coupling-device of the class described that is capable of production at av comparatively low cost, and adapted for 'manyluses, as for providingmeans for connecting various types of attachment with a source of fluid s ply.

A still further object of this inventionis to provide a coupling device of the class described, which may be readily connected or disconnected andwhich will, when connected, have an'abs'olutely fluid-tight joint Withthe above and other objects in view which will appear as the description proceeds, myinvention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the ap pended claims, it being understood that such changes in the precise embodiment of the itherebetween.
